Did your pronouns instantly switch in your head when you came out?

My gf came out as trans around a year ago. She said her pronouns in her head still haven't changed. Tbf neither have mine, but that begs the question: Is this the same way for everyone else in the trans community? She's been questioning her everything lately, and now even her transness. How was it for you? Was it easy for you to switch to the pronouns of your preferred gender in your head or did it take a long time like for us?
